In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1 to 3, an embodiment discloses an elbow connector, which includes a connecting piece 100 and an adapter sleeve 200, wherein the connecting piece 100 is used for installing a terminal 10 electrically connected to a cable, the adapter sleeve 200 is used for being sleeved outside the cable, two ends of the adapter sleeve 200 are respectively a sealing end 201 and an adjusting end 202, the sealing end 201 and the adjusting end 202 form an included angle, and the adjusting end 202 and the connecting piece 100 are rotatably connected.

In the elbow connector, the adapter sleeve 200 is sleeved outside the cable, and the sealing end 201 of the adapter sleeve 200 and the adjusting end 202 form an included angle, the cable can be guided and protected, the problem that the joint of the cable and the connecting piece 100 is easy to break due to bending is prevented, the cable can be stripped and the terminal 10 is formed by pressing the terminal 10 by a special tool, the terminal 10 is arranged on the connecting piece 100, since the adjustment end 202 of the adapter sleeve 200 is rotatably connected to the connector 100, when the terminal 10 of the connector 100 is inserted into the socket, the position of the connector 100 is fixed as the terminal 10 is inserted, and adapter sleeve 200 may adjust the position of adapter sleeve 200 relative to connector 100 based on the conditions at the installation site, namely, the adapter sleeve 200 is rotated, so that the adapter sleeve 200 or the cable does not interfere with other equipment on the installation site, and the connector can be connected more easily and is convenient to use.

Specifically, if the position of the plug with terminal 10 complex is lower, the distance of plug and ground is less, and conventional elbow connector is when inserting the plug, and the condition of contradicting appears in the partial structure of connector and ground, leads to the connector unable to use, and the elbow connector in this application, the position of rotatable adjustment sealed end 201 makes sealed end 201 not with ground contact, has guaranteed that elbow connector can normal use.

In one embodiment, as shown in fig. 1 to 3, a first matching portion 203 is provided outside the adjusting end 202, a butt hole is provided inside the connecting piece 100, a second matching portion 101 is provided on an inner wall of the butt hole, the adjusting end 202 is in plug-in fit with the butt hole, the first matching portion 203 is in concave-convex fit with the second matching portion 101, and the number of the first matching portion 203 and/or the second matching portion 101 is multiple.
